ls --color not working on freebsd?

[hanoii]

Hi!
So I have this Freebsd I am connecting to from mac, I already did the termcap addition and compilation of the database and while now most things work, I cannot get colors to work.

ls --color just output no color

on iTerm they do work. Any ideas?

I can reproduce the problem. kitty correctly respects the color escape codes. This can be verified with something like printf '\033[31mhello\n'. Executing ls --color > ~/test.txt in e.g. the gnome terminal, where color is working and then cat ~/test.txt in kitty also works, so for some reason ls does not work with the termcap.
For some reason adding

:Co#8:\
:AB=\E[4%dm:\
:AF=\E[3%dm:\
:op=\E[39;49m:

to the kitty termcap makes it work. I copied these from the entry for xterm-basic and removed all the unnecessary ones.
@hanoii Can you try appending the lines from above? You need to add a backslash to the last line printed by infocmp -C xterm-kitty.

[hanoii]

@Luflosi yes, that makes it work for me.

@kovidgoyal why does infocmp -C xterm-kitty not print these four things?

[kovidgoyal]

No idea, you'd have to ask the maintainer of infocmp

Not sure if this is related or intended (as Kitty's multi-platform), but on Linux, Kitty doesn't seem to support the $LS_COLORS variable so color support is missing from things such as zsh completions, ls (full range of file types) and commands like tree.

[kovidgoyal]

LS_COLORS is not something the terminal supports. It is something for programs running inside the terminal.

By default, infocmp -C will restrict the produced termcap output to 1023 bytes, and thus will throw out a lot of capabilities, including the four above. So I would recommend the following:

• make an uncut termcap file using infocmp -CrtqT xterm-kitty. It will contain the capabilities Co, AB, AF, and op, and many others.
• remove all capabilities you can live without until you fit into the 1023 byte limit.

Here is my attempt:

infocmp -CrtTq0 xterm-kitty | sed -e 's/:\(pa\|%1\|&8\|F[^12]\|K[1-5]\|[RS]A\|Z[HR]\|ac\|c[hv]\)[^:]*//g'

This produces the following termcap entry of 1022 bytes:

I've got no FreeBSD at hand to test it, so YMMV.

@tertium Is it necessary to limit the list to 1023 bytes?

I am trying to get this working on a FreeNAS host, and with the help of the comments in this thread it seems to work fine.
However, when using htop the output is not colored:

while it is when using htop inside an iocage jail:

While appending the termcap stuff made htop work at all, it is not colored on the host system.
Is this some configuration of FreeNAS/htop that disables colored output?
